Using a bittorrent seed works for quite a lot of linux distributions with lack of bandwith ... why then not doing this in this case.

Individual mirrors always make is necessary to distribute the patch ... making sure it's ok (checksum) and then the users need to try different mirrors with no feedback which mirror is best.

Setting up a tracker and then putting up like 2 - 3 main servers for releasing the patch would do all the jobs at once ...


However 20megs isn't that much as it couldn't be taken care of otherwise.
